If you have better ideas, but dont speak German, just ask! Also thats just needed, if you are going to use text within images which would make it hard for me to change. Otherwise just use English and I can change it myself.
As for the menu, just put item1, item2, whatever. I will complete all that.

Also if you could design the front page it would be great.
The front page should have
- a section for some text block with general hello stuff (like welcome to our site blah blah)
- then perhaps a news section (latest headlines)
- special offers (example: online casino X giving a special welcome bonus .)
- Top 5 online casinos (here you could design something nice looking, but basically it would be a 5 text links embedded in your design.
